She absolutely adores and the only meal she "tucks into" is char sui pork with char sui gravey!! Id love to be able to recreate that for her.

Any ideas based on her tastes I can expand.. Or tips to expand?

She's my second child and I've already tried lots of stragety.

Oh and shop brought only tuna and sweetcorn sandwiches

What about trying food she likes in different combinations? So she likes chicken and she likes spag bol so some sort of chicken pasta bake. If she likes that it might make her more willing to try new things

Pasta with tuna (or tuna mayo) and sweetcorn.
Scrambled eggs on toast.
Fajitas with chicken and whatever stir fried veg she will eat, with spices added.
Macaroni cheese.

She used to liked scrambled eggs then wouldn't touch it.
She only likes school macaroni cheese!
Won't touch faitits
